[espace]

hi,

in this snippet wich object "this" replace at this line, if i would write this  without "this" what must i write  :

        playerPapers5 = this.game.add.group()

the  part of the snippet :

var theGame = function(game){

	//////////////////////////////////////////////////////////////////////////////////////////
	//GROUP
	playerPapers5 = null
}

theGame.prototype = {
	create: function(){

		this.game.physics.startSystem(Phaser.Physics.ARCADE)

		playerPapers5 = this.game.add.group()

}

according to this code it means the game

menuState = {
    create: function() {
        game.world.setBounds(0, 0, 640, 360);
        var b = (game.add.image(0, 0, "menubg"), game.add.image(230, 200, "whiteplanemenu"));
        b.anchor.set(.5, .5);
        this.playbutton = game.add.button(428, 183, "playgamebutton", this.start),
        this.instructionbutton = game.add.button(428, 237, "instructionbutton", this.instruction),
        this.aboutbutton = game.add.button(573, 237, "aboutbutton", this.about),

    }
game = new Phaser.Game(640, 360);
game.global = {
    score: 0,
    bgm: new Object,
    gameoverbgm: new Object,
    ingamebgm: new Object,
    background: game.rnd.between(0, 4)
},
game.state.add("boot", bootState),
game.state.add("load", loadState),
game.state.add("menu", menuState),
game.state.start("boot");

hi douglas,

when i replace "this" by "game" i have an error.

I would replace this.game.add.group() with this.add.group();

but thats just how my games are set up...

ok thanks when i do

		playerPapers5 = game.add.group()

or

playerPapers5 = this.add.group()that works.

 

thanks both

i think that's what it means

this reference the game

i don't know if this fun fun function episode explain it better then that example with global objects that i understand just the half

this is usually the instance of the game state you are in, not the instance of the game.

@tips thx for engaging an interesting way of viewing phaser gamedev it should work in a term of process

The "this" in the first example refers to the current Phaser.State. The fact that you can call this.game.add the same way that you can call this.add is dictated by the fact that they both refer to the same thing (i.e. the state has a reference to an instance of Phaser.GameObjectFactory; the game has a reference to that very instance - and it's the same for a lot of other things).
